Chow Yun-Fat missed a helluva party April 9. The star of MGM’s “Bulletproof Monk” stayed home in Hong Kong, heeding travel warnings about SARS, but that didn’t stop the Lion from pulling out all the stops for the pic’s post-bow bash at Hollywood & Highland’s Grand Ballroom.

Revelers streaming in from the Chinese Theater preem were greeted by sparring martial artists and scenes from classic chopsocky films beamed onto curtains throughout the venue.

Vet musicvid helmer Paul Hunter, making his feature debut with “Monk,” said his main task was “to bring out the humorous side of Chow Yun-Fat,” whom he described as reserved and internal. That balanced nicely, he said, with co-star Seann William Scott‘s streetwise character.

Scott said the pic’s teacher-student relationship carried over to his own relationship with Chow. “I was adamant about doing everything right,” Scott said. “He’d say, ‘Sean, relax; have fun.’ “Partygoers included MGM’s Chris McGurk, Michael Nathanson and Erik Lomis; producer Charles Roven; plus guests including Will Smith, Sigourney Weaver, LL Cool J, Dwayne “The Rock” Johnson, Selma Blair, Jason Biggs and Red Hot Chili Peppers frontman Anthony Kiedis.
